Dry brown spots on my green Coleus leaves

[AmberVon]

You have all been so great helping me with my orchids! I figured maybe someone knows a thing or two about coleus.

I bought them grouped together in one little plastic pot when they were little. I replanted them in this large pot
and they've grown huge in a couple months.

In these pictures they are at work in my office because I'm going on vacation for over a week in a couple days and I asked a co-worker to plantsit a couple babies for me. At home, they are on our dining room table at west/north facing windows that we pull the blinds on during the late afternoon sun. I've never let them wilt or anything. I keep the soil moist. I have one of those glass globes in there to help with that.

We live in Southern California right on the beach so our humidity is pretty good.

The problem is the predominantly green plant. It has many many leaves with these brownish spots. The spots are dry and will crack if I touch them. I don't spray or mist the plant at all so they can't be water spots. I don't see any bugs at all on the plant and the other two plants look GREAT with no spots at all.

Any ideas?


Here are my pretty plants!
